Probability distributions of the half-light radii for the V-band (solid), soft X-ray (dash-dotted), and hard X-ray (dashed) emission considering different sections of the X-ray light curves. The top panel shows the results corresponding to the analysis of the 2006 data, the middle panel to the sparse long-term X-ray data, and the bottom panel shows the combined results. As in Figure 4, the gray area corresponds to predicted values of r _g .
